import java.util.ArrayList;
import java.util.Iterator;

public class Main {
  public static void main(String[] args) {

    ArrayList<String> aList = new ArrayList<String>();

    aList.add("1");
    aList.add("2");
    aList.add("3");
    aList.add("4");
    aList.add("5");

    Iterator itr = aList.iterator();

    // iterate through the ArrayList values using Iterator's hasNext and next methods

    while (itr.hasNext()){
      System.out.println(itr.next());
    }
  }
}
